CVE-2026-64456

A flaw was found in the Linux kernel's virtio-rng driver. A malicious or buggy virtualized hardware random number generator virtio-rng backend can report an overly large data length to the guest operating system. This unchecked length can lead to an out-of-bounds read, causing the driver to acces...

CVE-2026-23553

In the context switch logic Xen attempts to skip an IBPB in the case of a vCPU returning to a CPU on which it was the previous vCPU to run. While safe for Xen's isolation between vCPUs, this prevents the guest kernel correctly isolating between tasks. Consider: 1 vCPU runs on CPU A, running task ...
